Greg,
Here are the results I promised you. Sorry it took so long. I don't think
they are particularly interesting, perhaps more iterations, say 1000000?
If there are different options you would like to see let me know, I have all
5 kernels sitting on the machine and can keep it for a couple days. I
attached a simple bar chart to quickly summarize the data.
o testing 2.6.23.1-rt7 to 2.6.23.1-rt11 for ghaskins et all
o load used was building 2.6.23.1 make -j 16
o system:
- 8 Opterons @ 1.6 GHz
- x86_64
- 2 GB RAM
